pub.oauth:refreshAccessToken

Requests a new access token from the authorization server by using a refresh token. If the authorization server issued a refresh token to the client with the initial request, the client can use this service to request a new access token when the initial access token expires.

grant_type	String Specify the type of grant flow required by the client. For refresh tokens, you must specify refresh_token.
refresh_token	String Refresh token issued to the client by the authentication server.
scope	String Optional. Specify the name of one or more scopes required by the client. Use a space to separate multiple scopes. The value for scope must match or be a subset of the value you provided for the pub.oauth:authorize and pub.oauth:getAccessToken services. The scope of the refresh token can be smaller than the original request. It cannot contain any scope tokens that were not in the original request.

access_token	String The access token issued by the authorization server.
token_type	String The type of access token issued by the authorization server. The value is Bearer.
expires_in	String The number of seconds for which the access token is valid.
refresh_token	String The refresh token issued by the authorization server. You can use this token to obtain new access tokens using the same authorization grant.
scope	String Conditional. The name of the scopes requested by the client.

The pub.oauth:refreshAccessToken service must be invoked using HTTPS unless the Require HTTPS setting on the Security > OAuth > Edit OAuth Global Settings page is disabled.

Clients must invoke this service via an HTTP POST request unless the watt.server.oauth.requirePost server configuration parameter is set to false. When this parameter is set to false, clients can invoke this service using HTTP GET.

The token_type output parameter is always Bearer. The authorization server retains the information about the bearer tokens it issues, including the user information. When the client presents a bearer token to the resource server, the resource server checks with the authorization server to see whether the user is allowed to access the requested folders and services.
